Abstract: The present invention relates to a multi-channel provision system for a wired network. The multi-channel provision system of the present invention includes a tap-off unit (330) for dividing a frequency band, assigned to a wired network for network communication, and providing resultant frequency bands to respective subscriber units belonging thereto. An optical network device (100) is disposed at a node where one or more sectors, divided according to a number of subscriber units that enable network access through the wired network, branch off. The optical network device (100) provides a frequency band for network access to each sector so that a same frequency band is assigned to each sector, thus generating a multi-channel for the frequency band, and reusing the frequency band, assigned to the wired network, a number of times corresponding to the number of the sectors through generation of the multi-channel.

Abstract: Provided is a high-efficiency slim vacuum inhalation apparatus which cools heat generated from heat-generation sources without using particular heat radiation components, and a robot cleaner employing the same. The vacuum inhalation apparatus does not need particular heat radiation components since an impeller is closely adhered to a rotational shaft by a pair of washers and an impeller bushing, to thus avoid from sliding, and since an inhalation efficiency which is caused by a brushless direct-current (BLDC) motor increases, and thus power consumption decreases. Further, since a BLDC motor is incorporated in a vacuum inhalation apparatus so that the vacuum inhalation apparatus can be implemented into a slim type, a robot cleaner can be also compactly realized into a slim type.
